Thom Baguley points to the standardized or minimum LR (p381) to answer this question. The minimum LR represents a worst case scenario for the null in that it compares the LR for against the MLE of the observed data, i.e. the most likely (strongest) possible hypothesis supported by the data, and is defined as …
